Los Angeles police say a large kitchen knife may have been used in the apparent murder-suicide. 'It was really brutal,' one officer says.

The Los Angeles Police Department declined to say how each died, citing the preliminary nature of the investigation, but Capt. Bill Murphy said investigators found a large kitchen knife that they believe was used.

"It was really brutal," Murphy said. "I've been at the scene of hundreds of homicides, and this was easily one of the worst."

He said police psychologists were working with officers and others who came upon the crime scene.
